Answer:
The Earth's orbit around the Sun is an ellipse, but it does change shape. ... At other times, the ellipse is more pronounced so that the Earth moves closer and further away from the Sun as it orbits. When the Earth is closer to the Sun our climate is warmer and this cycle also affects the length of the seasons.

a student mixed a sample of urine from a person with benedict's solution and heated ,the colour changed to Orange. (b)what did the student conclude on the health status of the person
Answer:
The person has high blood sugar.
Explanation:
Because benedict's solution tests for reducing agents, and since it changed its colour, reducing sugars(like glucose) is present.
Which of the following would cause an error in DNA replication?
A. DNA polymerase pairing A with G
B. DNA ligase connecting chunks of DNA
C. Helicase making a replication fork
D. DNA polymerase checking the DNA
Answer:
A. DNA polymerase pairing A with G
Explanation:
Adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G).
DNA polymerase pairing A with G would cause an error in DNA replication. The correct option is A.
An error in DNA replication occurs when an incorrect nucleotide is inserted during the replication process.
DNA polymerase is responsible for synthesizing a new DNA strand by adding complementary nucleotides to the existing template strand.
It ensures the accuracy of replication by matching each nucleotide with its complementary partner (A with T and G with C).
If DNA polymerase pairs A with G instead of A with T, it results in a mismatched base pair.
This is considered an error in DNA replication since it introduces a mutation in the newly synthesized DNA strand.
The fidelity of DNA replication relies on the correct base pairing and proofreading mechanisms of DNA polymerase to minimize errors and maintain the integrity of the genetic information.
Thus, the correct option is A.

Does the Second Amendment need to be "revisited" in 2021? yes and why?
I need help pleasee
Answer:
It needs to be revisited because of the random acts of violence that it enables.
Explanation:
People that have access to weapons of mass destruction use them to kill people for no reason. For example, the sandy hook shooting, the recent Stoneman Douglas shooting, and the Christchurch shooting. All these shootings could have been prevented if there was stronger gun control. If people did not have access to automatic firing machine guns, less people would have died.

A typical virus is made up of 2 parts. Check all that apply.
A) Golgi Body
B) Nuclear envelope
C) Nucleic Acid
D) Capsid
Answer:
C) Nucleic Acid
D) Capsid
Explanation:
A virus is structure that is dependent on a living host to replicate itself. Viruses are majorly pathogenic in nature and have a structure that is made up of two parts namely: nucleic acid and capsid.
The nucleic acid, which can either be RNA or DNA holds the genetic information of the virus while the capsid is a protein coat that enclosed and protects the virus' genetic material. The capsid is also used during the infection life cycle of a virus where it helps the virus to attach to receptor cells on the host's cell membrane.

draw a line from each hormone in list A to the correct information in list B
Answer:
The correct answer would be -
FSH - used as fertility drugs to makes egg mature.
LS - stimulates the release of eggs.
Oestrogen - causes the lining of the womb to break down.
Explanation:
FSH is a hormone released from the pituitary gland and is the abbreviation of Follicle-stimulating hormone which controls the menstrual cycle and growth of eggs in ovaries. It is also used as a fertility drug that promotes the growth of eggs to mature it.
LS or Luteinising hormone is the hormone that is released from the pituitary gland and promotes the surge of the release of eggs.
Oestrogen is the hormone that helps females during puberty during the menstrual cycle to breakdown the lining of the womb.
Just as slow-moving water loses sediment, fast-moving water can pick up new sediment to carry. Which part of the river
bend will experience the greatest amount of new erosion? How will this erosion affect the shape of the river?
Answer:
The part of a riverbend that will experience the most erosion is the inside corner, this is because the water will be hitting it on two sides, the erosion will likely curve the inside corner more.
The water flowing at the maximum velocity and with the greatest ability to erode is on the outside of the curve, rivers that meander erode in both directions.
What factors affect the river?Cut bank erosion occurs when the edge of a stream channel bends, and it increases the loop of the meander, water that moves more quickly has greater kinetic energy.
It can therefore transport bigger particles, more articles may also be carried by it, and bigger and larger particles can be carried by a stream as it moves more quickly. The capacity of a stream increases with the size of the particles it can transport.
Therefore, a stream will have a quicker velocity if it has a steep slope or gradient, which implies it may transport heavier items in suspension.

You are a wild rabbit and your species currently lives in desert. Most of the rabbits are brown but there are a few that are white. An asteroid hits the Earth and the environment you live in suddenly becomes very cold. It begins to snow leaving snow covering the ground. Will your species be able to adapt and line in the new environment? Explain and give details (what happens to white rabbits and brown rabbits.)
I need the brainylest answer and I will give a brainylest answer for this.
Answer:
The species of wild rabbits that are brown would most likely have a harder time adapting than the white rabbits to the new environment.
Explanation: The brown rabbits are going to have a hard time living in the snow mostly because of their color. The brown rabbit is more likely to be able to live in the desert because they can camouflauge with their surroundings (the sand). Therefore, camouflaging in the white snow to escape a predator would be impossible for brown rabbits, since they could easily be spotted. Furthermore, the white rabbits would have a higher chance of survival since they can camouflage easier in the snow.

What is the effect of inputting stem cells instead of body cells into the original system?
Explanation:
Stem cell research indicates that s.cells are cells that are not fully developed; in turn if researchers inject a patient with type 1 diabetes into the pancreas the result is that the pancreas produces it's own insulin eliminating the chances of spikes in the blood sugars of the patient & also long term effects of high blood sugars that effect all vital organs & nervous system.
Researchers were also using stem cells to limbs that were amputated or damaged resulting in the limb regenerating itself.
I have seen a mouse that had a human ear attached to its body.
Researchers were ordered by our government to cease the experiments because pharmaceutical companies were making more $$ on medicines to supposedly help diabetics or veterans to live a normal life..
Fenómeno que consiste na combustão de grandes áreas florestais e conduz à libertação de grandes quantidades de CO2 para a atmosfera.
Answer:
Wildfires.
Explanation:
Wildfires is the phenomenon that causes combustion of large forest areas and leads to the release of large amounts of CO2 into the atmosphere. Wildfire occurs naturally as well as carelessness of humans that leads to the destruction of large area of forest and the habitat of wild animals also destroyed which compels them to migrate from that region. This wildfires produced high amount of carbondioxide gas in the atmosphere that is the main cause of air pollution.
